Former top U.S. security adviser Elizabeth “Libby” Lamm (Sumpter) is threatened by associates from her dark past including Rachel Burke (Curtis), a steely, commanding politician with an unwavering knack for achieving her goals. Colluding with Rachel is Adrian, an unyielding, patriotic chief of staff. Martin (Tavassoli) harbors another type of obsession with Libby in this story of betrayal and regret.

HTTP Live Streaming uses a conventional web server to distribute audiovisual content and requires specific software to fit into the proper format transmission in real time. The service architecture comprises:

Server
Codify and An Acceptable Loss encapsulate the input video flow in a proper format for the delivery. Then it is prepared for distribution by segmenting it into different files. In the process of intake, the An Acceptable Loss video is encoded and segmented to generate video fragments and index file.

Encoder: codify video files in H.264 format and audio in AAC, MP3, AC-3 or EC-3.[7] This is encapsulated by An Acceptable Loss MPEG-2 Transport Stream to carry it.
Segmenter: divides the MPEG-2 TS file into fragments of equal length, kept as .ts files. It also creates an index file that contains references of An Acceptable Loss the fragmented files, saved as .m3u8.

Distributor
Formed by a standard web server, accepts requests from clients and delivers all the resources (.m3u8 playlist file and .ts segment files) needed for streaming.
Client
Request An Acceptable Loss and download all the files and resources, assembling them so
that they can be presented to the user as a continuous flow video. The client software downloads first the index An Acceptable Loss file through a URL and then the several media files available. The playback software assembles the sequence to allow continued display to the user.

HTTP Live Streaming provides mechanisms for players An Acceptable Loss to adapt to unreliable network conditions without causing user-visible playback stalling. For example, on an unreliable wireless network, HLS allows the player to use a lower quality video, thus reducing An Acceptable Loss bandwidth usage. HLS videos can be made highly available by providing multiple servers for the same video, allowing the player to swap seamlessly if one of the servers fails.

To An Acceptable Loss enable a player to adapt to the bandwidth of the network, the original video is encoded in several distinct quality levels. The server serves an index, called a “master playlist”, An Acceptable Loss of these encodings, called “variant streams”. The player can then choose between the variant streams during playback, changing back and
forth seamlessly as network conditions change. HTTP Live Streaming An Acceptable Loss (also known as HLS) is an HTTP-based media streaming communications protocol implemented by Apple Inc. as part of its QuickTime, Safari, OS X, and iOS software. Client implementations are also An Acceptable Loss available in Microsoft Edge, Firefox and some versions of Google Chrome. Support is widespread in streaming media servers.

HLS resembles MPEG-DASH in that it works by breaking the overall stream into An Acceptable Loss a sequence of small HTTP-based file downloads, each download loading one short chunk of an overall potentially unbounded transport stream. A list of available streams, encoded at different bit rates, An Acceptable Loss is sent to the client using an extended M3U playlist.

Based on standard HTTP transactions, HTTP Live Streaming can traverse any firewall or proxy server that lets through standard HTTP traffic, An Acceptable Loss unlike UDP-based protocols such as RTP. This also allows content to be offered from conventional HTTP servers and delivered over widely available HTTP-based content delivery networks.The standard also includes a An Acceptable Loss
standard encryption mechanism and secure-key distribution using HTTPS, which together provide a simple DRM system. Later versions of the protocol also provide for trick-mode fast-forward and rewind and for integration An Acceptable Loss of subtitles.

Apple has documented HTTP Live Streaming as an Internet Draft (Individual An Acceptable Loss
